Is it possible to let CFX calculate a moving mesh (pre-defined mesh deformation: wall boundary layer moving), without doing the time consuming simulation. I want to do this predictions, so I dont get negative volumes or bad mesh during my calculation, so I have to totally redo it. It would be great if there is a trick to just get the mesh for every transient timestep without the equations solved. So in CFX post I just can see the mesh for every time step without of course the velocity field or other parameters that have to be solved. Note: its just mesh deformation, without FSI.

Yes, you can simply turn off the flow equations by using the expert parameters. Simply add this in your .def file and set each equation to false. This will solve a predefined moving mesh for the specified transient time. Unless your mesh is huge, this will be pretty quick and a good way to debug your model.
